Question

why do children / babies have more bones in body than the adults

Answer 1

Their bones are not well developed and they are attached to each other thus babies have more bones

Answer 2

hey dear Frnd....

 you may know, when a baby is born, and for some time afterwards they have a soft spot on their head. This soft spot is actually a gap between the bones. Yes, the skull is made up of separate bones. Over time, as the body grows they fuse together to make one single bone. This can actually be seen quite clearly on skull bones, with clearly visible lines where the different fragments have joined. The skull along with many other bones throughout the body fuse together as we grow up, reducing the total number of bones in the human body to 206..
